MP3802DH-LF

Lighting, Ballast Controllers Overview

The MP3802DH-LF-Z is a monolithic LED lighting driver IC designed for high-voltage EL lamp applications. It operates with a boost topology and accepts an input voltage range of 2.5 V to 5.5 V. The device generates a peak output voltage of 200 VPP, suitable for driving electroluminescent lamps. It functions at a fixed operating frequency of 250 Hz and provides a single regulated output channel. The component is housed in an MSOP-8 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Lighting, Ballast Controllers Feature Summary

• Integrated high-voltage boost converter specifically engineered for direct EL lamp excitation
• Fixed-frequency operation optimized for efficient electroluminescent panel driving
• Compact surface-mount packaging facilitates integration into space-constrained lighting modules

Lighting, Ballast Controllers Applications

• Electroluminescent (EL) lamp drivers
• High-voltage backlighting systems
• Specialized indicator lighting circuits

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix against official MPS documentation, as the provided model lacks the standard LF-Z designation found in distributor listings. Confirm current availability status directly with authorized channels, as supply constraints may apply to this specific part number variant. Ensure the ordering code matches the exact package and tape/reel requirements specified in the final datasheet.

Lighting, Ballast Controllers Selection Notes

Select this component when designing circuits requiring a dedicated driver for high-voltage electroluminescent panels rather than standard LEDs. The fixed 250 Hz frequency dictates the external component selection and acoustic performance considerations. Verify that the system input voltage remains within the 2.5 V to 5.5 V range to ensure proper regulation and protection circuitry activation.

Lighting, Ballast Controllers Part Context

This device belongs to the MP3802 series from Monolithic Power Systems, which focuses on specialized lighting driver solutions. Unlike general-purpose DC-DC converters, this series targets niche applications requiring specific high-voltage generation profiles for non-standard light sources such as EL wires or panels.

Lighting, Ballast Controllers Replacement Considerations

Consult official MPS substitution guides for verified alternatives. Generic boost converters lack the specific high-voltage EL driving characteristics required for this application.
